Objectives: The purpose of this study was to examine how the dentist's servant leadership affects the happiness index of dental hygienists. Methods: The subjects were 221 dental hygienists that have been working at dental clinics or dental hospitals. The data were analyzed using SPSS Version 20.0 (IBM Co., Armonk, NY, USA). An independent t-test and one-way ANOVA analysis were conducted to examine the difference in the happiness index of dental hygienists according to general characteristics. The independent t-test was conducted to examine organizational culture and happiness index according to upper and lower group based on the mean score for servant leadership. Pearson's correlation analysis was used to examine the correlation among key factors. Multiple regression analysis was conducted to identify factors influencing the happiness index of dental hygienists. Results: According to the analysis, there was a statistically significant positive correlation between the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists. However, a stewardship of the dentist's servant leadership factors was not found to have any correlation with the market culture. A multiple regression analysis was performed after including the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists. Meanwhile, the stewardship and community-building effect of the dentist's servant leadership had a statistically significant effect on the happiness index of dental hygienists. Consequently, a higher servant leadership factor in dentists was correlated with a higher happiness index of dental hygienists. Conclusions:The findings show that the dentist's servant leadership affect the happiness index of dental hygienists. Therefore, effective intervention and education programs related to the dentist's servant leadership and sound organizational culture are necessary to enhance dental hygienists' happiness index. Additionally, a follow-up study will determine the causal relationship among the dentist's servant leadership, the organizational culture and the happiness index of dental hygienists, considering organizational members and the environment of the dental clinics.

This study was conducted to determine the quality of sleep, and its association with the sociodemographic characteristics, health-related characteristics, and job-related characteristics among male workers in small-scale manufacturing industries with fewer than 50 members. A self-administered questionnaire was distributed to 856 male workers from April $1^{st}$ to June $30^{th}$, 2011. The survey items included the variables of sociodemographic, health-related, job-related, and quality of sleep. As a result, the quality of sleep according to the PSQI of the study subjects revealed 32.0% to be good and 68.0% to be poor. The quality of sleep assessed by hierarchical multiple regression analysis was significantly lower in the married group, those with lower BMI, and those with a lower level of subjective health status, non-smoking, alcohol drinking, without regular exercise, coffee drinking, blue color, had a longer of working hours, subjective health status, had a visiting out-patient department, and had a history of hospitalization. With the above model, the job characteristics had 13.1% explanatory power. This suggests that the quality of sleep (PSQI) has more power when combined with the job characteristics.

This study analyzed the changes in the industrial environment surrounding the Gumi region and the status of the industrial crisis in the Gumi area amid such changes. The Gumi region is experiencing a more turbulent period than ever in the environment changes at the international, national and local levels, such as the transition to the Fourth Industrial Revolution, the weakening of the competitiveness of key industries including mobile devices and displays, and the moving-out of core companies such as Samsung and LG Group. Accordingly, efforts have been made to diversify the industrial structure by fostering industry of automobile parts, high-tech medical devices and carbon materials to cope with and adapt to environmental changes at the regional level. However, the Gumi region is still locked in to the mono-cultural, large enterprise-dependent industrial structure centering on the mobile and display sectors, failing to overcome the regional industrial crisis and stagnating the overall local economy. The relocation of large companies began to increase in the 2010s, reducing the protection of large corporations against environmental changes at the corporate level. As a result, the crisis factors of small and mediumsized enterprises are gradually expanding to the national and international scale and working more complexly, which is beyond the level they can afford. So it is highly likely that the current industrial crisis will deepen. Therefore, it is necessary to strengthen the resilience to adapt to changes in the environment when it comes to overcoming the industrial crisis in Gumi region. To this end, it is necessary to improve innovation capabilities and diversify businesses based on convergence and complex technologies at the enterprise level, and to be selected as a special crisis response area aimed at creating an innovative ecosystem through autonomous resonance of companies and industries at the local level.

As the construction production system is reorganized as part of the construction industry innovation plan, direct construction is expanding. According to this trend, this study analyzed the impact and problems of the expansion of direct construction through the position of the construction industry and a study of foreign cases. In addition, by diagnosing the impact of the measures to expand direct construction from various aspects, countermeasures were suggested to suitably apply the direct construction mandatory system. Also, for each alternative, effects and problems were evaluated through interviews with experts in policy/administrative and architecture fields. The alternatives for expanding and improving the efficiency of the direct construction mandatory system derived from this study are four items: granting the discretion of the client, differentiation by scale of construction, utilization of construction guarantee system, and introduction of flexible working group leader system. As a result of the expert interview, all of them were evaluated to have a positive impact directly and indirectly on the expansion of direct construction. This study contributes literature to the application of the direct construction mandatory system by examining the current status of direct construction, and suggests a direction for expanding direct construction through deduction of alternatives for applying the direct construction mandatory system and expert evaluation.

Paradoxically, leadership has not only positive effects but also negative effects. The purpose of this study is to examine supervisors' dysfunctional leadership behaviors, antecedents and results in order to draw HRD implications for protecting organizations and employees from dysfunctional leaders and provide implications for leadership development. A qualitative research method based on semi-organized interviews with 28 employees from S-group was used. The results of this study show that the dysfunctional leadership behaviors were associated with ten behavioral categories: belittling and insulting the subordinates, authoritative and arbitrary behaviors, self-aggrandizement, biased preference for certain personnel, arrogance, micro-managing, inability to change and adapt, discordance between words and actions, over-dependance on supervisor, lack of ethics and values. Dysfunctional leadership behaviors were casually attributed to 'personal traits & experience', 'task characteristics', and 'internal & external environments of the organization'. Finally, the results of supervisor's dysfunctional leadership behaviors on employees and the organizational effects were 'increased turnover rate', 'declining work efficiency', 'collapsing morale', 'retraining innovative thinking', 'passive working culture', 'discouraging organizational vitality', 'discouraging organizational synergy', 'losing loyalty' and 'declining trust on supervisor'.

For long-term preservation of electronic records, the information on the whole processes of management from the time of creation of the electronic information should be captured and managed together. Such information is supported by preservation metadata thus the implementation of preservation metadata is important for preservation of electronic records maintaining the record-ness. Preservation metadata is the information that supports the process of digital preservation and functions th maintain long-term viability, renderability, understandability, authenticity and identity of digital resources. Preservation metadata should be developed applying the international standard Reference Model for an Open Archival Information System(OAIS) to have international interoperability for exchange and reuse. Initial international preservation metadata schemas were developed standardizing the OAIS Reference Model. But the preservation metadata schema of Victorian Electronic Records Strategy(VERS) and recently published Data Dictionary of PREMIS Working Group were developed in advanced types that are different from the existing framework. Those were advanced th practical ones from conceptual one. Comparing these two cases, proposed the elements of integral preservation metadata for long-term preservation of electronic records. This thesis has the significance that it has suggested the direction for future development of the elements of preservation metadata by setting the past discussions related to preservation metadata in order and proposing integral preservation metadata elements for long-term preservation of electronic records.

This study conducted a hierarchy analysis based on a questionnaire survey of experts in park management, ecosystem survey, and ecological environment planning to establish evaluation items and a weighing value of each item to develop ecological connectivity in Baekdudaegan mountain range neighboring the Taebaeksan National Park using the AHP approach. We selected four high-level evaluation indexes and 13 low-level evaluation indexes through literature review and interview with the people in the field and calculated weights for each question through the consistency analysis. The analysis showed that increasing the ecological value was the most important item with the index of 0.474 among the high-level evaluation items, followed by the mitigation of human-nature conflict at 0.247, participation by local residents at 0.165, and the economic perspective at 0.114. Among the low-level evaluation indexes, the movement route of wildlife was the highest at 0.116, followed by the connectivity of landscape ecological patch at 0.112, and functional habitat at 0.099. The comparison of the evaluation items in each working group and the weight factors showed that the movement route of wildlife was the most important at 0.116 in ecosystem survey, the functional habitat was the most important at 0.110 in park management, and the regional preservation and distribution of resources was the most important at 0.123 in ecological environment planning. The results of this study is useful to identify evaluation items for developing ecological network with a diverse source of the actual environmental data in the Taebaeksan National Park.

This descriptive research investigates the knowledge of and attitude toward HIV/AIDS among individuals in their 20s to 40s. This study also analyzes the results of the 2011 and 2013 community health surveys to identify the factors influencing their knowledge and attitude. The study subjects were 20 to 49 years old, and the final analysis included 182,315 subjects. The collected data were analyzed through t-tests, ANOVA, correlational analysis, and multiple regression analysis. The survey results showed a high level of knowledge of HIV/AIDS, with 69.4% correct answers. Most individuals lacked knowledge regarding routes of infection, and those in their 20s had the lowest percentage of correct answers. As for attitude toward HIV/AIDS, 44.3% showed a negative attitude. The scores for knowledge and attitude toward HIV/AIDS were higher among males, unmarried individuals, individuals with a higher income, individuals with a higher level of education, individuals working in agriculture, forestry, or fishery, managers, professions that were not homemakers/unemployed, and professional soldiers. A positive correlation (r=0.27, p<0.001) was observed between knowledge and attitude. The factors influencing AIDS knowledge and attitude were gender, marital status, income level, occupation, and education level. This study confirmed that there is a difference by age group. As such, educational programs customized by age and other characteristics are expected to be more effective in enhancing knowledge and in developing a more positive attitude towards HIV/AIDS.
